KIEV, May 21. /ITAR-TASS/. Leader of Ukrainian Communists Petro Symonenko said the Memorandum of Peace and Accord adopted by the Ukrainian parliament has contentious matters concerning the status of the Russian language, Ukrainian presidential election and arraigning the killers of peaceful protesters.

"The Communist Party (KPU) has not voted for the Memorandum because of these questionable points," the KPU press service quoted Symonenko as saying on Wednesday.

The Communist Party leader noted that the KPU had demanded "restoring order and public quiet in the country by stopping bloodshed and arraigning the killers of civilians during protests." This demand has not been met, Symonenko said.

The KPU also believes that it is inopportune to talk about the presidential election in the document because there are different points of view on the issue.

The Communists' official website said the KPU had insisted on the constitutional status of the Russian language.

Ukraine's Verkhovnaya Rada approved the text of the Memorandum of Peace and Accord on Tuesday. The draft of the document envisioned the suspension of the anti-terrorist operation in the country's southeast and return of the servicemen taking part in the operation to the places of their permanent deployment.

The finalized text of the Memorandum does not contain this provision. Instead, it urges law-enforcement bodies to prepare an action plan towards sending the troops involved in the military operation to the place of their permanent deployments on the condition of freeing of hostages and administrative buildings and disarming of all illegal paramilitary formations.
